"That makes you jump!" he said. "Well, now, at the end of that inquest business in the papers the other day I noticed Spencer Levendale's name mentioned in connection with some old book that was left, or found in Mr. Daniel Multenius's back-parlour. Of course, I concluded that he was the same Spencer Levendale I'd known out there in South Africa, five years ago. And to tell you the truth, I've been watching your papers, morning and evening, since, to see if there was any more news of him. But so far I haven't seen any."

Purdie and Melky exchanged glances, and in response to an obvious hint from Melky, Purdie spoke.

"We can give you some news, then," he said. "It'll be common property tomorrow morning. Levendale has mysteriously disappeared from his house, and from his usual haunts!—and nobody knows where he is. And it's considered that this disappearance has something to do with the Praed Street affair."

"Sure!" assented Guyler. "That's just about a dead certainty. And in the Praed Street affair, these platinum stud things are going to play a good part, and when you and your police have got to the bottom of it, you'll sure find that something else has a big part, too!"

"What?" asked Purdie.

"Why, diamonds!" answered the American, with a quiet smile. "Just diamonds! Diamonds'll be at the bottom of the bag—sure!"

There was a moment of surprised silence, and then Melky turned eagerly to the American.

"Mister!" he said. "Let's be getting at something! What do you know, now, about this here Levendale?"

"Not much," replied Guyler. "But I'm open to tell what I do know. I've been a bit of a rolling stone, do you see—knocked about the world, pretty considerable, doing one thing and another, and I've falsified the old saying, for I've contrived to gather a good bit of moss in my rollings. Well, now, I was located in Cape Town for a while, some five years ago, and I met Spencer Levendale there. He was then a dealer in diamonds—can't say in what way exactly—for I never exactly knew—but it was well known that he'd made a big pile, buying and selling these goods, and he was a very rich man. Now I and five other men—all of different nationalities—were very useful to Levendale in a big deal that he was anxious to carry through—never mind what it was—and he felt pretty grateful to us, I reckon. And as we were all warmish men so far as money was concerned, it wasn't the sort of thing that he could hand out cheques for, so he hit on the notion of having sets of studs made of platinum—which is, as you're aware, the most valuable metal known, and on every stud he had a device of his own invention carefully engraved. Here's my set!—and what Mr. Rubinstein's got there is part of another. Now, then, who's the man who's been dropping his cuff-links about?"

Purdie, who had listened with deep attention to the American's statement, immediately put a question.
